Adventures in Implementing a Testing Program

What are the ways in which a testing program can run aground? What are some suggestions for avoiding these problems?     

A subtraction experiment with six and seven year old children

This paper gives an account of an experiment involving 176 children of 6 and 7 years and their difficulties with subtraction problems. By using two screening questions, four levels of attainment were established and two teaching programmes were then devised to help the children forward to their next level. The results show that it is possible to assess a level of understanding in subtraction quickly and accurately and that, through the teaching programmes, pre-requisite skills needed to establish a sound foundation for subtraction can be taught. The experiment indicates, however, that an attempt to symbolise too soon is a danger to be avoided.     

The effect of socioeconomic background on earnings: a comparison by race

Consistent with previous studies, we find that family background variables exert significant indirect effects on earnings of both white and black males. In the case of blacks, parental income in particular exerts a significant direct effect on earnings. Education is found to be a much more important determinant of black earnings than white earnings, while job tenure has the reverse relationship. After adjustments, parental income and level of education exert the strongest effects on reducing the black-white earnings differential.     

Race and sex: teachers' views on who gets ahead in schools?

The research reported here was part of a large study of the impact of age, disability, race and sex on the teaching profession in England. The basic question asked in this research was how do these factors interact with career aspirations and achievements of classteachers, promoted teachers and headteachers? There were three different data sources: a large postal survey drawn from diverse geographic regions across England with over 2000 respondents; face‐to‐face individual interviews with over 100 teachers in 18 case study schools from across all of the main regions of England; discussions with special interest groups of teachers. Not surprisingly, the answer to the above question was complex. Nonetheless, the paper's conclusion highlights some of the noteworthy themes across this broad sample of teachers from primary, secondary and special schools.

Les travaux de recherche décris dans cet article ont fait partie d'une large étude sur l'impact de l'age, des handicaps, de l'origine ethnique et du genre sur les professions de l'enseignement. L'une des questions abordées dans cette recherche était de savoir comment ces facteurs interagissaient avec les aspirations professionnelles et les carrières des enseignants, administratifs et chefs d'établissement. Trois principales sources d'information ont été utilisées: un sondage par courrier de plus de 2000 personnes, couvrant différentes régions géographiques de l'Angleterre; des entretiens individuels avec une centaine d'enseignants de 18 écoles cibles, reparties sur les principales régions de l'Angleterre; des discussions avec des groupes de travail d'enseignants. De manière non surprenante, la réponse à la question ci‐dessus s'est avérée complexe. Néanmoins, cet article met en évidence un ensemble de thèmes significatifs à travers ce large groupe d'enseignants issus du primaire, du secondaire et d'institutions spécialisées.

La investigación que se presenta aquí formó parte de un largo estudio sobre el impacto que tenía la edad, discapacidad, diferencias de etnia y género en la profesión de maestro en Inglaterra. Una de las principales cuestiones a contestar en la presente investigación fue cómo estos factores interactúan en las aspiraciones profesionales de maestros, jefes del departamento y directores, se presentan en este artículo. Hubo tres principales fuentes de datos. Estas incluían: una amplia encuesta por correo la cual tuvo en cuenta diversas regiones de la geografía de Inglaterra, con cerca de unas 2000 personas encuestadas; entrevistas individuales cara a cara a unos 100 maestros en 18 estudios de casos de escuelas a través de todas las principales regiones de Inglaterra; y discusiones con grupos interesantes de maestros. No nos debe sorprender que las respuestas a las preguntas comentadas anteriormente fueran complejas de resolver. De todas formas las conclusiones del artículo dan luz a algunos de los temas significativos a través de la amplia muestra de maestros de escuelas de primaria, secundaria y escuelas especiales.

Die hier präsentierte Forschungsarbeit war Teil einer umfassenden Studie, die sich mit der Auswirkung von Alter, Behinderung, ethnischer Herkunft und Geschlecht auf den Lehrberuf in England auseinandersetzt. Die wesentliche Frage, die in dieser Forschungsarbeit gestellt wurde, lautete wie folgt: wie wirken sich genannte Faktoren auf Karriereaspirationen und Leistungen von Klassenlehrern, beförderten Lehrern und Schulleitern aus? Die Daten wurden aus drei Hauptquellen bezogen; dazu gehören: eine umfassende, geographisch breitgefächerte Postumfrage in England, auf die über 2000 Befragte antworteten; persönliche Gespräche mit über 100 Lehrern aus 18 zu Fallstudien herangezogenen Schulen in den Haupregionen Englands; und Diskussionen mit Lehrern, die bestimmte Interessengruppen vertreten. Die Antwort zu der oben genannten Frage war erwartungsgemäss komplex. Nichtsdestoweniger werden in dieser Arbeit einige der Themen hervorgehoben, die Lehrer aus dem Primär‐, Sekundär‐ und Sonderschulbereich für besonders erwähnenswert hielten.     

Scholarly Publishing in Korea: Language,Perception, Practice of Korean University Faculty

This study reports how internationalization of academic knowledge is reflected in the language choice of Korean academic journals across disciplines and examines perceptions and practices of eighty two faculty from various disciplines at three Korean universities concerning publishing in English journals. The results indicate that natural science has the highest percentage of English-medium journals whereas those in humanities and social science predominantly use Korean as a medium of publication. Similar disciplinary patterns are observed in the responses to survey questions about frequency of publication as well as desire and preference for publishing papers in English. The biggest motivation for Korean scholars to publish in English was the desire to reach global scholarly communities. Implications of these findings are discussed.     

Properties of the maximal correlation function

Sarmanov introduces the idea of maximal correlation function and applies it to his investigation of stationary Markov processes (1,2,3). We demonstrate some additional properties of the maximal correlation function as a measure of the dependence structure of stationary processes and present some applications of the maximal correlation function in generalizing applications of the usual correlation function to, for example, equivalent rectangular bandwidth and quadratic mean ergodicity.     

The impact of sequencing and prior knowledge on learning mathematics through spreadsheet applications

According to cognitive load theory, instruction needs to be designed in a manner that facilitates the acquisition of knowledge in long-term memory while reducing unnecessary demands on working memory. When technology is used to deliver instruction, the sequence in which students learn to use the technology and learn the relevant subject matter may have cognitive load implications, and should interact with their prior knowledge levels. An experiment, using spreadsheets to assist studient learning of mathematics, indicated that for studients with little knowledge of spreadsheets, sequential instruction on spreadsheets followed by mathematics instruction was superior to a concurrent presentation. The reverse was found for studients with more knowledge of spreadsheets. These results are explained in terms of cognitive load theory.     

Social functioning among college students diagnosed with ADHD and the mediating role of emotion regulation

Despite the many studies that have documented the association between symptoms of ADHD and social difficulties in children and adolescents, few have examined this phenomenon in college students. In addition, the underlying factors contributing to such social difficulties are still poorly understood. We hypothesised that college students with symptoms of ADHD, namely inattention and hyperactivity/impulsivity, would continue to display social behavioural difficulties, and that emotion regulation would play a mediating role in that relationship. Ninety-nine 17–24-year-old college students filled out three questionnaires to assess Inattentive and Hyperactivity/Impulsivity Symptoms, Social Skills, and Emotion Regulation abilities. Analysis revealed that emotion regulation is a significant mediator between Inattentive Symptoms and Social Skills for female students. There was no significant correlation between ADHD symptoms and Social Skills for males. Female college students report social functioning difficulties associated with their inattentive and hyperactive symptoms, and impaired emotion regulation abilities mediate this relationship for inattentive symptoms only.
